                    <p>虽然人们非常重视电动机和泵的选择，但选择连接这两个昂贵部件的理想联轴器的重要性往往被低估。</p>
<p>此外，安装和对中所选联轴器的正确程序经常被忽略。错误的安装和/或不受控制的不对中可能导致联轴器过早磨损和潜在故障，以及可能损坏泵和/或电机。</p>
<p>联轴器的基本功能是传递动力、适应不对中和补偿轴向运动（轴的端部运动）。有时，联轴器需要吸收冲击或振动。选择正确的联轴器取决于轴不对中或运动的四个基本条件：</p>
<p>1）当两个轴不共享相同的旋转轴时，会发生平行不对中。它们的端面可能是平行的，但是它们的轴心线彼此横向移位。</p>
<p>2）角度不对中适用于轴既不同心也不平行的情况。轴不对中的角度可以是对称的或不对称的。</p>
<p>3）当其中一根或两根轴显示轴向运动时，会出现端部浮动，即向内和向外移动。例如，带有滑动轴承的电动机在转子寻找绕组的磁力中心时“浮动”。温度变化也会导致热膨胀和轴位置的变化。</p>
<p>4）扭转挠性是指垂直于轴轴线的平面内的扭转运动。冲击或振动通常会导致这种情况。扭转挠性联轴器吸入并阻尼这些运动。</p>
<p>大多数挠性联轴器由两个法兰或轮毂组成，这些法兰或轮毂连接到被连接的轴上，以及一个可以是金属的连接元件（例如在盘式联轴器中）或由弹性材料制成的套筒，例如三元乙丙橡胶（EPDM）、氯丁橡胶、热塑性弹性体、氨基甲酸乙酯或机械连接，例如U-接头或齿轮连接。</p>
<p>对于弹性联轴器，应该能够处理平行和角度不对中。具有四向灵活性的联轴器可同时适应端面浮动和扭转运动。以下概述了各种可用的联轴器类型，提示了每种类型的优缺点。</p>
